The first set was very competitive but in the second set Li Na imposed her authority and Dominika was unable to step up to the challenge.
For Dominika it has been a great tournament and I am sure at the beginning of the tournament she probably didn't see herself in the final.
So getting to the final would have improved Dominika's ranking and she will hopefully build on this success to win a grand slam soon.
For Li Na she would have come into this tournament at least expecting to get to the semi-finals.
So winning her second grand slam I am sure exceeded her expectations and she will hoping to build on this success for the remaining grand slams of the year.
It was by no means a classic final but aLi Na was fortunate enough not to face a top twenty player on route to the final. But all that means is the draw opened up in favour and made this win possible.
